摘要： The present invention relates to a hydraulic door drive for a lifting door (1) that opens, in particular, vertically, comprising at least one hydraulic motor (6), adapted and configured to drive a door curtain (2) or to be at least concomitantly driven by the door curtain (2), at least one hydraulic unit (10) for supplying the hydraulic door drive (5) with pressurized hydraulic fluid (13; 13a), characterized by a pressure accumulator (22), wherein a) potential energy of the door curtain (2), which is released when the latter is closed, can be stored in the form of pressure energy in the pressure accumulator (22), and/or b) the pressure accumulator (22) can be loaded with pressure energy by means of the at least one hydraulic unit (10), wherein c) pressure energy stored in the pressure accumulator (22) can be discharged to the hydraulic motor (6) in order to at least open and/or at least close the door curtain (2).

摘要： The invention relates to a rolling gate (100), in particular a high-speed rolling gate, comprising: a door leaf (110) in the form of a flexible curtain, lateral guides in which lateral edges of the door leaf (110) are received, and a drive (140) which generates a driving force for driving the door leaf (110), wherein the door leaf (110) has an elastically designed terminating element (112) on a forward edge which is tensioned between the lateral guides by means of laterally applied transverse force components.Said rolling gate (100) is in particular characterized in that the driving force of the drive (140) engages on the terminating element (112) of the door leaf (110) and thus provides the laterally applied transverse force components for tensioning the terminating element (112) of the door leaf (110) and a tension force component substantially directed in the movement direction of the door leaf (110) for closing the door leaf (110). An improved rolling gate (100) is thus achieved which has high operational reliability and represents less danger to people or objects in cases of collision.
